The envelope refers to a thick paper jacket of a letter or a book. The purpose of the envelope is to insert a single sheet or specimen into the envelope to form an integrated set of document material.

However, in actual use of the prior art, the existing certificate clamping structure is inconvenient for clamping the certificate because the opening is formed in the surface of the envelope plate, so that four corners of the certificate are easily exposed outside and are easily polluted and wetted, and the hardness of the certificate is reduced.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a certificate envelope for conveniently holding a certificate, so as to solve the problems of the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: a certificate envelope facilitating the holding of a certificate, comprising an envelope sheet having a top and a bottom portion glued by glue to a bottom extension, said bottom extension being folded back over the surface of the envelope sheet by glue, said bottom extension having a surface which is knife stamped with an arcuate opening.

Preferably, the number of the bottom extension portions is two, and the two bottom extension portions are vertically symmetrical with respect to a center line of the front cover of the envelope sheet.

Preferably, the number of the arc-shaped openings is four, and the four arc-shaped openings are distributed at four corners inside the envelope plate.

Preferably, the number of the envelope plates is two.

Preferably, the wrapper plates are all of the same material.

Preferably, the size of the envelope plate is 218mm by 308 mm.

Compared with the prior art, the utility model has the beneficial effects that:

1. the certificate envelope clamping structure comprises an envelope plate, a bottom extending part, a certificate clamping structure and a cover plate, wherein the envelope plate is provided with an arc opening, the bottom extending part is connected with the bottom extending part through the arc opening, and the cover plate is provided with a plurality of arc openings;

2. the two envelope plates are arranged to be folded in half, when a certificate is inserted into the arc-shaped opening, the envelope plate on the left side can be turned over to cover the envelope plate on the right side, and the certificate can be protected between the two envelope plates.
